SELF-FEEDER EXTENSION FOR THRESHING-M ACHIJS I'ES.

Specification of Letters Patent.

Patented Sept. 19, 1916.

Application filed May 1.1, 1914. Serial No. 887,918.

To all whom it may concern:

Be it known that I, Hnnnn CAn'rnR CoMnR,

- a citizen of the United States, residing at Lehi city, in the countyof Utah and State of Utah, have invented a new and useful Self-FeederExtension for Threshing-Machines, of which the following is aspecification.

This invention relates to extensions for the self feeders of threshingmachines.

One of the objects of the present invention is to provide an extensionwhich is hingedly connected to the feeder and'which is of the same Widthas the feeder so that a smooth unbroken surface is provided along thefeeder and its extension, thus-preventing loss of grain between themeeting ends of the feeder and its extension and alsoinsuring theuniform feeding of material to the machine and, consequently, increasingthe efiiciency and capacity.

A further object is to provide an extension which does not require aseparate support while in use and which, while not in use, can be foldedback against the threshing machine and readily transported from place toplace with the machine.

Another object is to provide an extension in which travels the sameconveyer chain as is used within the feeder, means being providedwhereby this chain will be held in place while the structure is beingfolded or unfolded, without dan er of becoming tan gled,

With the foregoing and other objects in view which Will appear asthedescription proceeds, the invention resides in the com-,

bination and arrangement of parts and in the details of constructionhereinafter described and claimed, it being understood that changes inthe precise embodiment of the invention herein disclosed, can be madewithin the scope of What is claimed, without departing from the spiritof the invention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :Figure 1 is a side elevation of a portion of athreshing machine and showing the feeder and-its extension appliedthereto. Fig. 2 is an enlarged side elevation of the feeder andextension folded against the threshing machine, a portion of saidmachine being illustrated. Fig. 3 is a longitudinal section through thefeeder and extension, parts being broken away. Fig. 4 is an enlargedtransverse section through the extension, said section being taken onthe line A-B Fig. 3. Fig. 5 is a plan View of the rear end portion ofthe extension, the

conveyer 'chainbeing removed and the chain holding tongues being shownin engaging position. Fig. 6 is a plan view of one of the chain guidesused in connection Wlth the structure.

Referring to the figures by characters of' reference 1 designates aportion of a threshing machine having the usual inlet structure 2 towhich the trough-like feeder body 3 is hingedly connected as at 4, anysuitable means, such as a latch member 5, being provided for engagingthe body 3 to support it in extendedor active position, as shown inFig. 1. A hook 6 or the like can be employed for engaging the'body 3when the same is folded inwardly and upwardly as shown in Fig.2. Thisbod 3 s provided with the usual brace rods 7 or holding it in extendedposition, as shown in Fig. 1.

. The feeder extension constituting the present invention, includes atrough-like body 8 of the same cross sectional contour and proportionsas the body 3 and having one end adapted to fit snugly against the outerend of the body 3 so that, when the extension is in active position, itssidewalls will constitute practical continuations of the side walls ofthe body 3 while its bottom will be flush with and constitutepractically a continua tion of the bottom of the body 2.

Secured to the outer faces of the sides of the bodies 3 and 8 arereinforcing straps 9 extending upwardly to the upper meeting corners ofthe two bodies 3 and 8 where they are pivotally connected so as to formhinge connections between the body 3 of the feeder and the body 8 oftheextension. The hinge connections have been indicated generally at 10.

As shown in Fig. 4, the bottom of the body 8 is provided, at each side,with a longitudinally extending shallow channel 11. As before pointedout, the body 8 is of the same cross sectional contour as the body 3.Consequently'these channels 11 in the body 8 will register withcorresponding channels 1n the body 3. These channels are designed toreceive the upper flights of endless chains 12 which extend aroundsprockets 13 located adjacent the inlet of the threshing machine andalso extend around sprockets 14 secured to a shaft 15 which isjournaled, at its ends, in boxes 16 slidably mounted within slottedguides 17 extending from the outer end of the extension body 8. Springs18 are fitted in these guides and bear against boxes 16, thus serving tohold the boxes pressed toward the enter ends of their guides 17, asshown in Fig. 2.

lhe chains 12 are connected by cross strips 19 provided with teeth 20 ofthe usual form whereby a conveyer is produced, the cleats or strips 19being adapted to slide upwardly along the bottoms of the bodies 3 and 8thus to guide the grain up to the inlet of the thresher. The lowerflights of the chains 12 ride upon idler sprockets 21 supported belowand by the body 3. Another idler sprocket 22 can be arranged under eachchain at a point under the inlet 2 and each chain 12 can also be trainedover an additional idler sprocket 23 supported by and under theextension 8.

A holding tongue 24 is pivotally connected to the bottom of the body 8at the outer end thereof and is adapted to be shifted either intoposition under the bottom of the body, as shown by dotted lines in Fig.5, or to be moved outwardly into the position shown by full lines insaid figure and at which time it will engage one of the cross strips orcleats of the conveyer and hold the said conveyer against movement alongthe bottoms of the bodies 3 and 8. A deflector or guide is preferablyarranged adjacent each of the sprockets 13. Each of these deflectors orguides is in the form of a plate 25 having spring fingers 26 whichreceive the sprocket between them, these fingers fitting close to thehub of the sprocket and being extended between the lower flight of thechain and the sprocket supporting structure, as shown in Fig. 3. Thus itwill be seen that the chains are pre-' vented by these fingers 26 fromwrapping about the sprockets and becoming entangled.

Instead the fingers 26 will force the chains off of the sprocket teethwhile the chains are moving in the direction indicated by the arrow inFig. 3.

\Vhen the mechanism herein described is in use, the feeder. body 3 isextended as shown in Fig. l, the same being held in such position by therod or rods 7 and by the latch or latches 5. Furthermore, the body 8 ofthe extension is supported in alinement with the body 3 and the feederbody 3 is relieved of the weight of the body 8 by a removable support 27which may be connected to said body 8. A conveyer made up of the chains12 and cross strips 13 is operated by the same mechanism as the shorterconveyors which have heretofore been extended solely throughout thelength of the body 3 and this conveyer is adapted to entirely displacethe shorter conveyer referred to. During the operation of the conveyerthe material placed in the body 8 of the extension will be engaged bythe conveyer and drawn upwardly along the bottom of said body 8 and ontothe bottom of the body 3 and thence into the threshing machine,importance being attached to the fact that there are no spaces betweenwhich grain will fall and thus become wasted, and to the further factthat both the extension and the feeder are of the same width so thatgrain can thus be uniformly supplied to the machine. Should it bedesired to fold or collapse the structure, as when .the machine is to bemoved from place to place, it would merely be necessary to remove thesupport .27, fold the body 8 upwardly and rearwardly onto the body 3after moving the locking tongue 24 into engagement with the conveyer,and then to unfasten the body 3 at its upper end so that it will be freeto swing downwardly and inwardly-to the position shown in Fig. 2, itbeing understood that the two bodies 3 and 8 are held together by a hook28 or the like. When the parts are folded to the position shown in Fig.2, they can be held by the hook 6. It will be seen that by mountingthe-conveyer in the manner described itcan be folded readily withoutbecoming displaced and, by utilizing the holding or fastoning tongue24:, the chains will be kept upon the sprockets and parts 10, come.quently, be restored to their active positions without any. great laborsuch as would be required should the conveyer chains become displaced orentangled.

What is claimed is The combination, with a feeder body for threshingmachines, of an extension hingedly connected toand adapted to swingdownwardly into position under the body of the feeder and upwardly intoalinement therewith, said extension including hingedly connectedtrough-like sections foldable with Q the wheels carried therebycooperating to In testimony thatI claim the foregoing as hold the chainagainst displacement relative my own, I have hereto affixed my signaturethereto when the parts are folded, a tongue in the presence of twoWitnesses.
